The rootcause is the colon in iscsi target name iqn.2003-01.org.linux-iscsi.fedora121.x8664:sn.712a3704dac7 passed to qemu as %3A by libvirt.
Is this an issue?
Could you give me some advise to debug this problem ? I can provide more information if need.
Libvirt (or rather libxml2 which is used for URI formatting) escapes special characters, but libiscsi doesn't decode them. This seems to be fixed in libiscsi git, but it hasn't been released yet: https://github.com/sahlberg/libiscsi/commit/e061cba1 Jan
